It’s staggering to think that Matthew Scott Hunter came up with a way to combine his love of clean floors and Star Wars before the marketing teams at Disney, Lucasfilm, and iRobot did. Using random household items he turned his functional robot vacuum into an Artoo unit that roams and cleans his home.
Inspired by a very droid-looking bin they spotted in a garage, Hunter started with a lightweight bin for his droid’s body and domed head, which was then upgraded with legs made of stiff poster board, and a bunch of random household items for details and greebling. Given the shape of the robot vacuum used for the droid’s front foot, Hunter couldn’t make a perfect replica of R2-D2, so instead opted to make a custom astromech droid, R9-D9, with a slick paint job that would make Iron Man tempted to ditch JARVIS.
The entire droid ended up weighing in at around 14 pounds, which was light enough for a robot vacuum to pull it around Hunter’s house without significantly reducing its battery life. To further help bring his creation to life, an oscillating fan was sacrificed to make R9-D9's domed head turn back and forth, while a Bluetooth speaker hidden inside, powered by a portable battery, plays droid sounds as the robot goes through its cleaning routine.
The upgrades mean there are lots of places the robot vacuum can no longer clean, including under couches and tables, but that seems like a minor sacrifice to make for an Artoo unit of your own that actually helps out around with the chores.
